DESCRIPTION

Dust collector comprising a handle unit and intended for a vacuum cleaner

Technical field!

The invention relates to a dust collector for a vacuum cleaner, the dust collector comprising a centrifugal separation assembly configured to separate the dust contained in the air introduced through a first inlet; a dust box unit to collect the separated dust in the centrifugal separation.

Background Technique!

A vacuum cleaner is designed to separate the dust by means of centrifugal separation. Said vacuum cleaner may include a centrifugal separator to separate the dust (or impurities) using the centrifugal force and a dust collector that includes a dust box configured to store the separated dust.

The dust collector is generally mounted on the vacuum cleaner and should be detached and removed from the vacuum cleaner when it is necessary to discharge the dust stored in it or to clean the dust collector. Thus, the dust collector includes a grip piece for its movement. Furthermore, the dust collector is configured in such a way that the upper and lower units of the same can be separated from each other when the dust (impurities) stored in it is discharged or during its cleaning.

Therefore, the dust collector must have easy coupling / separation between the upper and lower units, as well as easy movement or fixing / separation of the dust collector with respect to the vacuum cleaner and also, it must keep the units firmly coupled together. upper and lower. In this regard, in a wet-type dust collector filled with water to remove dust, it is more necessary for the upper and lower units to be fixed.

For this reason, a conventional dust collector can include a locking unit, which can firmly hold a grip piece, a centrifugal separation assembly and a dust box coupled together, and can also easily allow the separation of the mentioned components .

Examples of related art may include the Korean Patent with registration number of. 560332 (related technique I), Swiss Open Patent Publication No. 688734 (related technique II) and European Patent No. EP1062900 (related technique III).

Related art I discloses a dust collector in which the coupling between a cyclone unit (centrifugal separator) and a dust box 120 is released when a user presses a button while grasping a transport grip piece provided in the powder box. Next, when the user moves a handle of the coupling / detaching gripper piece to a predetermined position and then lifts the handle, it is possible to detach the cyclone unit from the powder box.

Related art II discloses a dust collector to which a bar is attached in close contact so that it can rotate at one end of a handle and a distal end of a lateral protrusion installed in a powder box. When the close contact bar performs a crank action according to the position of the handle, a filter chamber can be separated from the dust box.

Related art III discloses a dust collector in which a lid is attached to a tank by coupling between the lifting means provided on the lid and a handle.

However, the related techniques I to III described do not disclose a function to fix the handle or the grip piece without risk of rotation and, therefore, entail the problem that the handle or the grip piece can be unnecessarily shaken in a Lock state released, causing inconvenience in use.

On the other hand, due to the fact that the related techniques I to III described do not disclose a function of fixing the handle or the grip piece in a locked state released without risk of rotation, there is a problem that the collected impurities or water they can leak through the unwanted opening of a centrifugal separation assembly, causing secondary contamination.

US 2008/000004 A1 discloses a vacuum cleaner having a formed body with a mounting space. In a top region of the mounting space, a cyclone cylinder is fixedly installed. A dust collection container can be inserted into a lower portion of the mounting space. On a lower outer surface of the dust collection tank, a lift / lower unit is mounted. When the dust collection tank is placed in the mounting space, the lift / lower unit can be actuated to raise or lower the dust collection tank relative to the bottom wall of the mounting space. If the dust collection tank is lifted, it may come into close contact with a lower end of the cyclone cylinder.

A vacuum cleaner dust collector according to the preamble of claim 1 is already known, eg, from European patent EP-A-1728460.

The handle unit 100 includes a handle 101 ', a handle coupling member 130 formed in the centrifugal separation assembly 200 and a bracket 150.

The handle 101 'includes a grip piece 101, grip piece support bars 101a, rotatable coupling members 120, clamp levers 103, clamp pieces 104 and latch pieces 105 formed in the centrifugal separation assembly 200.

The grip piece 101 is shaped so that it can be easily grasped. The support bars of the grip piece 101a respectively extend downwards from the opposite ends of the grip piece 101.

The rotatable coupling member 120 and the handle coupling member 130 are configured to rotatably connect the gripper support bars 101a to the lateral surfaces of the centrifugal separation assembly 200, respectively. The configurations and functions of these components will be described in more detail in the following description with reference to Figures 4 to 6.

The clamping levers 103 extend downward from the corresponding rotatable coupling members 120, so that they rotate together with the rotary coupling members 120. The clamp pieces 104 are respectively formed at the lower ends of the clamping levers 103. Fixing pieces 104 perform a locking function to prevent centrifugal separation assembly 200 from detaching from powder box unit 300.

Latch pieces 105 are provided on an outer surface of a first centrifugal separation tube 200a in positions facing the corresponding fastening parts 104. Accordingly, when the centrifugal separation assembly 200 and the powder box unit 300 are positioned In such a way that they lock each other, the latch pieces 105 can respectively be coupled to the fixation pieces 104. This being the case, the fixation piece 104 and the latch piece 105 can be hooked together with interference fit, holding hook or the like.

The handle 101 ', as described, may be coupled to the centrifugal separation assembly 200 to move the centrifugal separation assembly 200, or it may serve to mount the centrifugal separation assembly 200 securely on the dust box unit 300 or separate her from it. Specifically, the handle 101 'can be rotated around the centrifugal separation assembly 200 until the fixing part 104 and the latch part 105 are coupled together to fix the centrifugal separation assembly 200 to the powder box unit 300 , or it can be rotated to release the coupling between the fixing part 104 and the latch part 105.

To this end, the rotatable coupling member 120, as illustrated in FIG. 4, it takes the form of a disk, which is coupled to a lower end of the grip piece support bar 101a and has an outer peripheral rib 120a protruding from its entire outer circumference. A rotatable shaft 123 protrudes from the center of a rear surface of the rotatable coupling member 120 to rotatably fit into the coupling member of the handle 130. The first to third attachment protrusions, 121a, 121b, and 121c, are arranged in a imaginary circle having a predetermined radius from rotary axis 123 such that a first clamping recess 122a and a second clamping recess 122b are defined between the first to third clamping protrusions, 121a, 121b and 121c. As will be described later, a leaf spring fixing projection 134a 134 (i.e., an elastic member) installed in the coupling member of the handle 130 is inserted into any one between the first fixing recess 122a and the second fixing recess 122b, to stop the rotation of the support bar of the grip piece 101a. Furthermore, a guide protrusion 121a is formed in the same circle in which the first to third raised fastening protrusions, 121a, 121b and 121c are formed, in a position opposite to the first to third raised fastening protrusions, 121a, 121b. and 121c. The guide projection 121a serves not only to rotate the rotatable coupling member 120, but also to support the rotary coupling member 120.

A recess is provided in the handle coupling member 130 at the center of an internal surface thereof. Rotary Shaft Coupling 133, wherein Rotary Shaft 123 is rotatably adjusted. A crossbow seat recess 132 (i.e., an elastic member seat recess) is further formed in a region adjacent to an inner circumference defining the coupling recess of the rotary shaft 133, so that the crossbow 134, of the protruding fixing projection 134a, sits in the recess of the crossbow seat 132.

A fixing protrusion guide groove 131a and a guide protrusion slot 131b, which are arcuate in shape, are arranged in an imaginary circular line having the same radius from the rotating shaft coupling recess 133 as that of the rotating shaft 123 in positions opposite the first to third fixing lugs, 121 a, 121b and 121c and the guide lug 121d, so that the first to third fixing lugs 121a, 121b and 121c are inserted into the fixing lug guide groove 131a so that they can rotate within a predetermined angle range and the guide boss 121d is inserted into the groove of the guide boss 131b so that it can rotate within the predetermined angle range. In this case, the crossbow seat recess 132 is located in the portion of an arcuate inner edge of the guide groove of the fixing projection 131a so that it communicates with the guide groove of the fixing projection 131a.

In the case that the rotatable coupling member 120 and the handle coupling member 130 have the configurations as described, as illustrated in FIG. 6, the rotary shaft 123, the first to third fixing projections 121a, 121b, and 121c and the guide projection 121d of the rotary coupling member 120 are rotatably inserted into the rotary shaft coupling recess 133, the guide groove of Fixing protrusion 131a and guide protrusion slot 131b of handle coupling member 130, respectively.

The fixing projection 134a is inserted into any one between the first fixing recess 122a and the second fixing recess 122b according to a direction of rotation of the handle 101 ', thereby acting to stop the rotation of the handle 101'. In this way, it may be possible to prevent unwanted rotation as well as excessive rotation of the handle 101 '.

Next, the functions of the rotating coupling member 120 and the handle coupling member 130 to prevent excessive rotation of the handle 101 'and stop the rotation of the handle 101' in a locked state and in a state of lock released.

During the rotation of the handle 101 ', the clamping projection 134a can be selectively inserted into the first clamping recess 122a or the second clamping recess 122b, as illustrated in FIG. 6 thus stopping the rotation of the handle 101 '.

Specifically, when the grip piece 101 is rotated counterclockwise to secure the centrifugal separation assembly 200 coupled to the powder box unit 300, the fastening boss 134a is inserted into the first fastening recess 122a , thus stopping the rotation of the handle unit 100.

Unlike the above description, when the grip piece 101 rotates clockwise to separate the centrifugal separation assembly 200 from the powder box unit 300, the clamping projection 134a is separated from the clamping recess 122a, and It is then inserted into the second clamping recess 122b, thereby stopping the rotation of the handle 101 '.

With the described operation, the rotary coupling member 120 and the handle coupling member 130 can function not only to prevent excessive rotation of the handle 101 ', but also to stop the rotation of the handle 101' in a locked state , as well as in a released lock state.

The centrifugal separation assembly (200, see FIG. 2) includes a first inlet 201, an exhaust chamber 270, a partition 250, a first centrifugal separation tube 200a, a first exhaust pipe unit 210, a plurality of second centrifugal separation tubes 210a and a plurality of second inlet pipe units 230 communicating with exhaust chamber 270. In this case, partition 250 divides the interior of the centrifugal separation assembly into an upper region defining a second flow path 240 and a lower region defining a first centrifugal separation area 200c and a plurality of second centrifugal separation areas 210c.

The first inlet 201 is located on a side surface of the centrifugal separation assembly 200, to allow outside air directed from a brush assembly (not shown) from the vacuum cleaner to enter the first centrifugal separation area 200c.

The exhaust chamber 270 is located on a side surface of the centrifugal separation assembly 200 in which second exhaust holes 252 are formed to discharge the air that has passed through the second centrifugal separation tube 210a, so that all the seconds Exhaust holes 252 are located in the area of the exhaust chamber 270. With the configuration described above, the exhaust chamber 270 functions to collect the discharged air from the second exhaust ports 252 and discharge the air to a motor unit of vacuum cleaner fan (not shown) (not shown).

The first exhaust pipe unit 210 is a cylindrical pipe, which is provided with a guide 203, a grid 211 having exhaust holes 211a, and a sealing member 220. As the introduced air swirls in the first unit of exhaust pipe 210, dust is separated from the air. The resulting air, from which the dust has been removed, is discharged through the grid 211. The sealing member 220 fits into a water distribution opening 501 of a water distribution channel 500 and serves to isolate the channel water distribution 500 of a first wet type dust collection area 300c.

The plurality of second centrifugal separation tubes 210a define the second centrifugal separation area 210c therein. Once the air discharged from the first exhaust pipe unit 210 has been introduced into the second centrifugal separation tubes 210a through the second inlet pipe unit 230 communicating with the second inlet 231, the second exhaust pipes Centrifugal separation 210a separates the fine dust contained in the air and discharges the resulting air into the exhaust chamber 270 through the second exhaust port 252 drilled in a position superior to the lateral surface of the centrifugal separation assembly 200. The plurality of seconds Centrifugal separation tubes 210a are arranged in parallel on the side surface of the first centrifugal separation tube 200a and are integrally formed with each other to communicate with each other through a second flow path 240.

A configuration of the water distribution channel 500 is disclosed in detail in Korean Patent Application No. 2009-0043736 filed by the disclosure application, and therefore a detailed description thereof will be omitted herein.

FIG. 7 is a perspective view illustrating a state in which the centrifugal separation assembly 200 and the powder box unit 300 of FIG. 1 are separated from each other. Next, a coupling relationship between the centrifugal separation assembly 200 and the powder box unit 300 will be described with reference to Figures 2 to 7.

Centrifugal separation assembly 200 having the configuration as described, as illustrated in FIG. 7, is configured to engage or detach from the top of the powder box unit 300. When the centrifugal separator assembly 200 is coupled to the powder box unit 300, the dust collector 1 of FIG. 1.

In this case, when the centrifugal separation assembly 200 is coupled to the powder box unit 300, the first centrifugal separation tube 200a and the first powder box 300a are coupled to each other and define a first separation structure A.

Each of the second centrifugal separation tubes 210a and each of the second powder boxes 310a define a second centrifugal separation structure B '. Each second centrifugal separation structure B 'serves to separate fine powder that has not been separated in the first separation structure A. A combination of a plurality of second centrifugal separation structures B' defines a second separation structure B in which impurities, such as fine powder and the like, which have not been removed in the first separation structure A, are removed.

As described, after the centrifugal separation assembly 200 is coupled to the powder box unit 300, the handle unit 100 is rotated counterclockwise to a position to hold the separation assembly 200 centrifuge and 300 powder box unit coupled together. By rotating the handle unit 100, as the fixing part 104 and the latch part 105 are coupled to each other, the centrifugal separation assembly 200 and the powder box unit 300 can be fixed to each other without risk from separation. In such a state, when the clamping member of the gripper 150a of the holder 150 is fitted to the gripper 101, the handle 101 'is locked to rotate. Furthermore, since the elastic rib support piece 152 applies pressure to the elastic rib 151, both ends of the elastic rib 151 defining an opening come into close contact with each other, thus accumulating elastic restoring force.

When the dust collector 1, which is assembled as described, is mounted on the vacuum cleaner (not shown), the exhaust chamber 270 is connected to a channel that communicates with the fan motor unit (not sample) from the vacuum cleaner (not shown). Also, the first inlet 201 is connected to an inlet channel (not shown) that is connected to the brush assembly (not shown). With this configuration, the dust collector 1 defines a channel for the air flow inside the vacuum cleaner (not shown).

Then, when the vacuum cleaner starts to operate, the outside air is introduced through the first inlet 201 and, subsequently, the impurities, such as dust and the like, contained in the air are separated in the first centrifugal separation area 200c and the second centrifugal separation areas 210c. The separated impurities are collected in the first wet type dust collection area 300c and the second wet type dust collection area 310c.

The resulting air, from which the impurities have been removed in the first centrifugal separation area 200c and the second centrifugal separation areas 210c, is directed to the exhaust chamber 270, thereby discharging to the fan motor unit (not shown ) of the vacuum cleaner.

Then, when it is desired to separate the centrifugal separation assembly 200 from the powder box unit 300 to discharge the water containing the impurities collected from the powder box unit 300 or to clean the powder box unit 300, the Fixation of the grip piece 150a is separated from the grip piece 101. In this case, the elastic rib 151, which has been compressed by the elastic rib support piece 152, returns to its original shape by the elastic restoring force accumulated therein, thereby causing the clamping member of the gripper 150a to rotate and release from the gripper 101. In addition, the elastic rib 151 serves to keep the clamping member of the gripper 150a released from the grip piece 101.

Once the coupling between the grip piece fixing member 150a and the grip piece 101 is released as described, the user can rotate the grip piece 101 clockwise. In this case, when the fastener 104 is rotated clockwise and released from the latch 105, the centrifugal separator assembly 200 can be detached from the powder box unit 300.

When a locking operation or a locking release operation is performed after coupling the centrifugal separation assembly 200 to the powder box unit 300, as described, the rotating coupling member 120 and the coupling member of the Handle 130 can operate to prevent excessive rotation of handle 101 'and to stop rotation of handle 101' in a locked state or in a released lock state.

Although the dust collector 1 has been described as having the described configuration and function, as a wet type dust collector, the dust collector 1 can function as a dry type dust collector when not filled with water W. Furthermore, in the case where the dust collector 1 is a dry type dust collector, the second separation structure B can be omitted.
